The article presents the construction and properties of variable damping shock absorbers, achieved through the use of a so-called bypass valve. The change in the damping force of these shock absorbers is obtained by using a proportional solenoid valve. A brief classification of semi-active shock absorbers and the results of our own research on the characteristics of such a shock absorber are also presented. The influence of the range of variability of the shock absorber damping forces on the range of variability of the dimensionless suspension damping coefficient level is shown.Shock absorbers with adjustable characteristics allow for the construction of a suspension with variable damping. The nomenclature for this type of suspension is diverse due to a number of classification criteria – e.g., due to the applied method of damping regulation, the response speed of active elements, the frequency range enabling effective operation of such a suspension, or the approach to control.
